To all whom t may concern.'

Be it known that l RALPH H. GRANT, a citizen of the United states of America, re-

siding at Dayton, county of Montgomery,

y and exact desbription.

This invention relates to improvements in storage batteries and particularly to that type of storage battery wherein the'battery plates are suspended trom the cover ot the batteryl j ar.

The general practice in the manufacture ot batteries is to suspend the battery plates from the cover. These covers are made oi non-conducting and acid proof materials. rlhis material is generally fragile. The *Weight oli the battery plates causes the covers to sag and break easily, especially when the battery jars are not handled carefully;

@ne of the objects of the present invention is to provide a support for the battery' plates which will substantially relieve the strains on the co er.'

Another object "of the present invention is to reduce the quantity of non-conducting material, such as rubber, necessary for covers.

One manner of carrying out these objects is to provide a support `of relatively high mechanical strength, mounted on the cover, which-rfilltalie up the bending strains, and the weight of plates to the battery jar walls through the cover, the cover being subject Ato compression strains only.

and for ner obfectslof the present invention will be apparent from the 'follow- 'inb cription, wherein a preferred embodiment is described, reference being had to the following. drawing.

lin the drawing:

The ligure is a sectional View ci the battery a cover and a Support member mounted thereon, and a J iront elevation. view oil the battery plates mounted in the batterv ieri .Y

airing tc the drawing, the numeral 20 indicates the battery jar or container, 2l a cover oit non-conducting material for the jar, and 22 the electrolyte thereinwrL support 23, preferably made of Wood is mount: ed upon the cover 2l. The positive and 'negative' battery plates 24 are insulated from each other and attached to terminals 25 and Patented May 2,

26, respectively. The terminal 2.6, which is` l. shown behind the terminal. 25, is mounted'.v in the same manner as the terminal 25. Holes 27 are provided inthe cove-r 21, which 'are in alinement With the holes 28 providedin the support 23. Terminals 25 and v26 are provided with screw threaded portions which` 26, and when said nuts are in their proper .project through the holes 27 and 28;'f'lp`hej clamping nuts 29. engage terminals 25;

place they will clamp the cover 21 andsupthe plates in position. At the bottom of the.

port member 23 together' and rigidly secure r battery plates a bolt 30 is provided and en tends through the battery plates and isk adapted to cooperate With the sides of the jar, thereby eliminating any unnecessary motions of the battery plates.

l't will be apparent that the vmanner of.'

supporting the battery plates herein described has advantages over the batteries of the usual construction. @ne of these ad' vantages is that the bending strains due to the Weight` of the battery plates are taken up principally by the support member, thereby preventing the cover from sagging and breaking. A

'Due to the tact that the entire Weight of the battery plates is on the supportmember and not on the fragile cover, except at the walls of the j ar, the amount of materialfcomarising the cover can be reduced beyond that which would be required, if the cover alone were made strong enough to support the plates.

".nother advantage possessed by this inw vention is apparent when for any reason the fragile cover should be broken, the support will prevent the battery plates from dropping to the bottom of the container, and will prevent the breaking of the container.

l/Vhile the Aform of the structure herein shown and described, constitute the preferred form et embodiment in the present in vention, it is to be understood that other forms might be adopted.l all coming Within container; a support removably mounted or. said cover, said support projecting over the Walls of the container; and a set of battery cover, said support being constructed and arranged to prevent the battery plates from dropping down to the bottom ofthe container if the cover should be broken, and including a hole through which thel battery y plate terminal projects; and means cooperating with said terminal -to suspend the plates 'upon said support.

4.' In a battery, the combination with a. icontainerfor the electrolyte; of means for supporting the battery plates within the container and means 'cooperating with the battery plates and tliecontainer'to prevent lateral movement of the plates therein.

5. In a battery, the combination with a container; oi a support mounted on said container 'for carrying the battery plates; and means adjacent the bottom of the battery plates and cooperating with the sides of the container to prevent lateral movement of the plates therein.

In testimony whereof I affix my signature.
